SPECIFICATION forming part of Letters Patent No. 340,279, dated April20, 1886 (No model.)

To all whom it may concern;

Be it known that I, LUOIUS BRIGGS, of Glasgo, in the county of NewLondon and State of Connecticut, have invented certain new and usefulImprovements in Condensers for Steam- Engines, ofwhich thefollowingisafull, clear, and exact description, reference being had to theaccompanying drawing, forming part of this specification.

My invention relates to the class of condensing steam-engines whichcondense the exhauststeam by injecting the same into a chamber, where itis brought in contact with a jet of water. In these engines it becomesnecessary to provide means whereby the water of condensation from thecondensed steam and the water from the cold-water injector forcondensing the steam are readily and effectively removed from thecondensing-chamber.

The object of my invention is to provide what I may term individualcondensers" for each exhaust-valve of the steam-cylinder, and which areworked automatically, each in conjunction with its connectedexhaust-valve, so that the complete system of my condensers is operatedand controlled by the steam valve cut-off motion.

To the above purposes my invention is in the nature of the combinationsand sub-combinations of theessential parts, as hereinafter fullydescribed and claimed.

The accompanying drawing illustrates an elevation of an ordinarysteam-cylinder with a portion of the steam-pipe and engine-frame, andwith my improved condenser shown in section as attached below thecylinder and extending below the floor 40.

Referring to the said drawing, 1 designates the steam-supplypipe leadinginto the steamcylinder 2, which is clothed with a wooden jacket, andhaving the portion 3 of the engineframe extending from one side. At thetwo upper corners of the figure are located the steam-valves 4 and 5,respectively, which are in turn connected to the governor of the engineby the bars 6and 7. (Shown in portions.)

The stems of the steam-valves 4 and 5 are each provided with acrank-arm, 8, keyed to them. At the two lower corners of the figure arelocated the exhaust-valves 9 and 10, respectively. The stem of theexhaust-valve 9 is provided with an approximately Y- shaped crank,-11,

and the stem of valve 19 is provided with an Lshaped crank, 12. Upon theshaft 13, fixed upon the side of cylinder 2, is looselyjournaled thewristplate ll, which is something 6f a balloon shape, and has its smallend connected suitably with the rocker-shalt 15, which is in turnconnected with the main eccentric. (Not shown.) The wrist-plate 14hasloosely mounted thereon four wrists, 16, from which run the rods 17,which are jointed to the valve-stem cranks 8 8, ll, and 12,respectively.

It is evident that these above-described connections operate in theusual manner of the well-known form of Corliss engine to control I theinduction and eduction of the steam driving the piston.

The following description relates to the construction of my improvedcondenser. The exhaust-pipes 18 lead from the exhaust- ,ports of thevalves 9 and 10, respectively, into the chambers 19, which are smallcylindrical condensingchambers with the injectors 29 projecting throughtheir outer ends and lying in their long axes. These injectors 20 aresuitably perforated upon their uppcrsurfaces, and have their outer endsconnected with the cold-water-supply pipes 21, and are provided with theordinary rotary valves, 22, have keyed to their stems the cranks 23, theother ends of which are fastened one to the Y- crank 11 and the other tothe L-crank 12 by means of the rods 21. From the lower sides of thechambers 19 lead the pipes 25, which are shown as screwed into themouths of the valve-casings 26, which are suitably shaped like smallcylinders, and have therein the rotary valves 27 ,which open and closethe communication between the condensing-chamber l9 and the main 33,into which the valve-casings 26 open from their lower sides. This which8:

main 33 is an ordinary pipe-main which leads to the hot-water tank. (Notshown.) The rotary valves 27 are rigidly fastened to the cranks 28,which are connected by movable joints to the rods 29, both of which areloosely jointed to the disk 30. The disk 30 is mounted and turns on thefixed journal31, directly below the journal 13 of the wrist-plate 14.The disk 30 is connected upon one side loosely to the rod 32, which islikewise connected at its other end to the wrist-plate 14. All thesedescribed connectingrods which connect the wrist-plate with the variousvalves, and the exhaust with the injector-valves 22, and thecondenser-valves 27 with the disk 31, and the disk 31 with thewrist-plate 14, operate in a mutually reciprocating and rocking manner.

In the position shown by the figure the steam-valve 4 is opened and itscorresponding exhaust-valve,9,is closed,its injector-valve 22 isclosed,and its condenser-valve 27 opened.

Considering the right-hand condenser, the

steam-valve 5 is closed, its corresponding exhaust-valvc, 10, is opened,its injector-valve 22 is opened, and its condcnser-valve 27 is closed.These condensers alternately operate one at a time, and a description ofone will suflice for both. Referring to the right-hand condenser, thepiston (not shown) in cylinder 2 having reached the limit of left-handtraverse, the steam-valve is closed, the exhaust 2o 10 is opened,likewise the injector-valve 22 (to inject the water-jet through theperform t-ious into the chamber 19) and the condenser valve 27 isclosed. The exhanststeam flowing through the exhaust-valve 10 is carriedonto the injector 20, which sprays the cold water whereby theexhaust-steam is condensed, and the resulting water of condensation andwater from the injector together gravitate from chamber 19 to pipe 25,where it remains confined by valve 27. XVhen the rocker-shaft 15 is nowdrawn to the extreme left, the wrist plate 14 turns on its shaft andcomn'iunicates motion to all its connected parts. Then the piston is atitslimit of right-hand traverse and 35 the condition of all the valvesis reversed from the order above described, and the wateriiow-s" outfrom the righthand condenser. being released by eondenser-valve 27, andinto the main 33, which subsequently conveys it to the.

0 hot-water tank.

It is obvious that my condensers are autostance, if necessary for themore perfect operation of the condenser in discharging the waste water,there may be substituted for the oneway valves 22 threeway valves whichopen into the little air-vents 50. (Shown in broken lines.) This willoperate to admit sufiicient air into the condensing-chamber at theproper moment to drive the water out into the main 33.

Having thus described my invention, I claim as newai'iddesire to secureby Letters Patent- 6 5 '1 In a condenser, the injector eoacting andconnected with its corresponding exhaustvalve. substantially as setforth.
